SAMUEL T. WILSON, OF CHARLESTON, WEST VIRGINIA, ASSIGNOR OF ONE-THIRD TO JACK- SON CARR AND ONE-THIRD TO H. W. SENTZ, OF CHARLESTON, WEST VIRGINIA.

SHAKING-SCOURER.

To all whom it may concern:

Be it known that I, SAMUEL T. Winsov, a citizen of the United States, residing at Charleston, in the county of Kanawha and State of WVest Virginia, have invented certain new and useful Improvements in Shaking-Scourers and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in vibrating grain scourers.

The object of the invention is to provide a grain scourer having means whereby the grain will be thoroughly cleaned and scoured, and separated from the impurities and the other matter removed therefrom.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side View of the vibrating grain scourer constructed in accordance with the invention," Fig. 2 is a vertical cross-sectional view and Fig. 3 is a horizontal sectional view of the same.

Referring more particularly to the drawings, 1 designates the scourer which consists of a supporting frame 2 in which is arranged a series of inclined scouring trays or tables 3, said tables being arranged one above the other and inclined in opposite directions, as shown. The trays ortables 3 are supported in position at their opposite ends by brace bars 4. The stack of trays or tables thus secured together are yieldingly supported in the frame 2 by means of spring metal supports 5 which are secured at their lower ends to the base of the frame and at theirnupper ends to the under side of the lowermost tray or table.

Mounted in suitablebearings on the front end of the frame 2 is a transversely disposed crank shaft 6 on one end of which is arranged a drive pulley 7 by means of which the shaft may be connected with and driven from any suitable operating crank of the shaft 6 is connected the inner end of a pitman-rod 8, the opposite end of which is secured to the adjacent end of the lowermost tray or table 3, whereby when the shaft is driven the stack of trays or tables Specification of Letters Patent.

will be reciprocated or vibrated to cause the grain deposited thereon to travel over the surface of the trays.

Near the lower end of each of the trays or tables 3 is formed a transversely-disposed passage 9 in which the grain is discharged from one tray to the next lowest tray and through which the cleaned grain of the lower tray or table is discharged into a suitable receptacle not shown. In the bottom of each of the trays or tables 3 adjacent to the discharge passage 9 is arranged a screen or sieve 10 through which the scourings or other matter removed from the grain is adapted to pass. Below each of the screens 10 is arranged a trough 12 by means of which the scourings passing through the machine is carried off to the side of the machine.

011 the bottom of each of the trays or tables 3 is arranged a series of longitudinallydisposed ribs or bars 13, said ribs or bars and the surface of the trays between the same being covered with emery. 14 or other abrasive material. The emery or other abrasive material is preferably applied by covering the bottom and ribs 13 of the trays with ducking or canvas which is given a coating of glue and then sanded or covered with emery to produce an abrasive surface. As this abrasive surface becomes smooth from use, the same may be readily sanded or coated again in the manner described. The ribs 13 are provided to increase the abrasive surface over which the grain passes.

Arranged at the higher end of the upper tray or table is a distributing box or hopper 15 into which the grain to be cleaned is placed and from which said grain is fed and evenly distributed over the surface of the upper tray or table through discharge passages 16 provided at the lower edge of the inner side of the hopper and communicating respectively with the several channels formed between the ribs 13.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new, is

In a grain scourer, the combination with a frame, a plurality of superimposed trays differently inclined with respect to each other flexibly mounted for reciprocatory movement within said frame, a pair of connecting bars, one at each end of said trays, a hopper connected to the upper tray and provided with a plurality of apertures, a plurality ofribs in each tray, the ribs in the top tray forming channels which register with the apertures in the hopper, abrasive material upon the ribs and the bottoms of said trays,

a screen at the lower end of each tray, a refuse receptacle below the screen, together with chutes adjacent the screens which communicate with the succeeding trays below, and means for imparting reciprocatory motion to all of the trays uniformly.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
